Introduction An enzyme is a protein with a special shape, which catalyses or speeds up chemical reactions inside our bodies. However not all enzymes are proteins. The enzyme amylase that I will be using throughout nbsp; The effect of enzyme concentration on enzyme activity.
The writer has a reasonable grasp of the theory behind the practical. As a class we collected Optimum temperature is the temperature at which an enzyme produces the highest reaction rate. Students know enzymes are proteins that catalyze biochemical reactions without altering the reaction equilibrium and the activities of enzymes depend on the temperature, ionic conditions, and the pH of the surroundings.
Understand the enzyme Catalase. Catalysts naturally, lower the activation energy required for reactions. The lower the activation energy is, the faster the rate of reaction is, and therefore enzymes speed up reactions in the body by lowering the activation energy required. Enzymes S-cool, the revision website?
Enzymes are biological catalysts. They speed up chemical reactions in all living things, and allow them to occur more easily.
They occur in plant cells and animal cells. Without them we would not be alive. Although they work powerfully, enzymes are just chemical molecules, made up of proteins. They are nbsp; Investigating an enzyme-controlled reaction: Hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell.
Cells make the enzyme catalase to remove hydrogen peroxide. Free enzymes Essays and Papers — papers, essays, and research papers. Introduction Enzymes are proteins that are used to accelerate bio chemical reactions.
Through this essay I will go through some examples of each case, and explain the complexities of these examples. Hydrogen peroxide is released due to many metabolic reactions in the body, which gives toxicity to the living cells.

Following a coursework review by QCA, controlled assessment has been introduced as part of nearly all new GCSEs, to replace coursework. Don't panic, I got 36/36 on my most recent science in the news without a massive amount of preparation.
Make sure you've actually done extra calculations to find out something which isn't immediately obvious from the data; you get a lot of marks for that.
